RH1498M
10MHz, 6V/µs, Dual
Rail-to-Rail Input and Output
Precision C-Load Op Amp
DESCRIPTION
The
RH1498M
is a dual, rail-to-rail input and output pre-
cision C-Load™ op amp with a 10MHz gain-bandwidth
product and a 6V/µs slew rate.
The RH1498 is designed to maximize input dynamic range
by delivering precision performance over the full supply
voltage. Using a patented technique, the input stages of
the RH1498 are trimmed, one at the negative supply and
the other at the positive supply. The resulting guaranteed
common mode rejection is much better than other rail-to-
rail input op amps. When used as a unity-gain buffer in front
of single supply 12-bit A-to-D converters, the RH1498 is
guaranteed to add less than 1LSB of error even in single
5V supply systems.
With 110dB of supply rejection, the RH1498 maintains its
performance over a supply range of 4.5V to 36V. The inputs
can be driven beyond the supplies without damage or phase
reversal of the output. These op amps remain stable while
driving capacitive loads up to 10,000pF.
The wafer lots are processed to Linear Technology's in-
house Class S flow to yield circuits usable in stringent
military and space applications.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
A heat sink may be required to keep the junction temperature
below this absolute maximum rating when the output is shorted
indefinitely.
Note 3:
Matching parameters are the difference between amplifiers
A and B.
Note 4:
Output voltage swings are measured between the output and
power supply rails.

The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown as the final electrical test in accordance with method
5004 of MIL-STD-883. The verified failures of group A, subgroup 1, after
burn-in divided by the total number of devices submitted for burn-in in
that lot shall be used to determine the percent for the lot.
